Battleping subscription work on timecard that you can get from offgamer website, you can download battleping from battleping website. I use to use it but for some reason if I use battleping now it won't let me load the character selection screen and I was too lazy to troubleshoot. Since my ping without it is fine.

Go to Guild on server in the menu, you can search for the guild then apply for it

You need to be in a guild that is a member of one of the 3 alliance. No rank requirement.

Vault is only open at certain time of the day depending on the alliance competition though.

You do not craft gear to gear up your own character, you get all gear from dungeon. The only gear worth crafting is the BIS gear, Lucid in current patch, google it and you will it takes a lot of farming.

You should only touch crafting when you reach level cap which is 65, because yes it is costly to level and you do not need any crafting stuff when leveling. Making pots is probably the easiest, etching is quite good but random dependent, other crafting profession not much use unless you plan to craft materials to sell, mostly those that players need for BIS gear.

What you can do while leveling is gathering, since it doesn't require anything beside pressing a button you can do that easily.

Crafting lucid and tensus doesn't require crafting skill, anything below those yes you would need crafting skills but they are not worth to craft.

If you want to craft to earn gold, etching, potions and scrolls is where you should look at. Bear in mind you do need to have substantial amount of gold before you can really craft, especially etching since some materials drop in dungeons but in low amount. Potions and scrolls is easier since you can gather the materials yourself with high enough gathering skills, but higher level recipe drop in dungeon as well so those are not easy to get.

Crafting for own use is still viable, things like HP pots, MP pots, eclipse potion, crit power scroll from recipe that you can get from the crafting merchant are not too expensive to craft, just make sure you gather your own materials.

But yeah for now concentrate on dailies, saving gold and stuff, until you have extra gold that you can spend on crafting.

Yeah just gather all mobs and let the DPS aoe them fast, though if you get more than 1 brawler you get someone who bullrush the pack you already gather and bring it somewhere else lol but only happen when leveling.

Tanking using brawler is fun, you never stop attacking and since your attack can be glyph to counter, you seldom need to counter manually.

Nope still a lot of brawler around, go dungeon 9 out 10 is brawler tanking

The MY/SG guild is Darkness Reborn, you can apply in-game.

Been having random dc past few days, in dungeons and outside as well, same thing happens to my guild mates, so probably the game or tmnet is acting up lol
